FRANK r. DUNN, or

ANDERSO I DIANA, ASSIGNOR' TO THE ANDERSON TOOL COMPANY, OF ANDERSON, INDIANA.

- SCALE.

To (ill whom it may concern: I

Be it known that I, FRANK P. DUNN, of Anderson. county of Marion, and State of Indiana, have invented a certain new and useful Scale; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

- The object of this invention is to improve the construction of scales'bot'hiof the weight and value type, and especially the means for operating the scale and causing it to prop-' erly indicate the are weighed, which vary or other unit.

One feature'of the invention consists in providing a horizontal scale beam. with in price-per-pound prices per-pound or other unit graduations,

thereon, and means, such as a poise, movable on sand beam for regulating the action of the indicating means and causing it to indicate the total value of any article being weighed atany unit on said scale beam to which the poise orothers'liding means might be set. To that end all that is necessary in this scale is to have a single rowof total graduations to which the indicator points and which will make the proper value calculations when the poise is moved to the price-per-poundpr other unit indicated on the scale beam while the article is being weighed. 1

In connection with the value. indioefii g" means a pound scale can beemployed id is here shown so that the scale will int icate article when the pois'o'n the price-per-nnit scale beanr is moved'to its normal position. Therefore, with, this scale -onefca"n immediately determine the weight and also thevalu'e of an. article or either the weight or value,

to a single row of graduations. the tw'oj'sets of numerals being parallel so that the .same indicator will point to both series-of numerals."

a Another aaag 'br the invention consists in the 'employn the indicating m ans, one of said levers be ing infiue'ncedby the load and transmitting the .i flucnce oft-he load to the indicating means so'as to'cause or permit the actuation is provided'with means for variably invalues of articles as they as desired, andthe value and weight numerals to be applied ;axially, and they move oppositedirections. As hereinshown the nt of a plurality of levers, I

inner end of the indicator controlling lever each separatelyNrnd flexibly connected with Specification of Letters Patent. Patented Feb, 21, 1911. Application filed March 18, 1908. Serial No. 420,850.

fluencing theindicating means so as to regulate its action. Tothat end said last mentioned lever, in the form of the invention herein shown, has a price-per-unit scale beam connected with it with a poise on said beam for causing such variable influence on the indicating means. But independently of or in addition to this means for varying the in,-

: fluen'cesof said indicator controlling lever,

the connection between said lever with the indicating means is and may be suchflas to enable said lever to exert a variable influence upon the indicating means -as the sameis actuated. In the-form herein shown the load-influenced lever is' so connected with the indicating means-as to actuate it, while the indicator-controlling lever is weighted atits inner end and is provided at such end with aconnection leading to the indicating means so as to act in opposition to said loadinfluenced' lever. Thus in the form shown herein the connection between the indicating means and the lever for controlling the indicator normally pulls the support down from the axis of the indicating meanswhen the latter is at zero but asthe indicator is moved from zero, the influencethereo'n of said in: dictator-controlling lever is gradually increased by the end of said lever gradually moving away from a vertical line through the axis of the indicating means in a direction opposite to the connection between the indicator and load influenced lever,

\Vhile herein thereis shown a load-influenced lever with a load-"receiving member mounted thereon between the fulcrum of said lever and the end thereof connected with the indicating means, it is not desired to limit the invention to a levermounted on said principle and which" directly actuates the indicating means.

A further feature of theinvention consists in mounting the two said levers so that they r are substantiallyparallel with, each other. and in fact, one extends and operates withinthe other and they are .fulcrumed cosimultaneously and 'moves in the same direction as the load,

while the inner end oftheload-influenced member moves. in an, opposite direction, but I this relation might be reversed.

ings and the following description and cla1ms2- In the drawings Figure 1 is a side elevation of the scale with the parts, thereof in their idle position, Fig. -2 is a planview of the left hand part of the base,'parts being broken away. Fig. 3 is a horizontal section on the line 33 of Fig. 1,, showing some of the hidden parts by dotted lines. Fig. 4 IS the same as Fi 3 with the indicating means and the in icator-controlling means removed so as to show the load-influenced for the load-receiving member, the load-- guidingrod being partly broken away.

Referrin now to the details of the construction of the scale herein shown to illustrate said invention, there is base 10 having an upwardly extending. rectangularcasing or-housing 11 open on its front and rear sides, said openings being closed by-removable 'lates 12,.the central ortions of'which are ormed of glass and tie outer portions of metal. Through these glass plates the inner ends of the levers and their operation is visible. The upper part of the casing or housin 11 is fan-shaped like the usual fan-sha 5 scale audit is open. likewise 011 each si e, and both sides closed with glass plates 14, see Fig. 6, held in place between the sides of the casing or housing and the center plate 15 from which there is a down-v wardly extending plate or chart 16 about one inch in width and on each side of this plate or chart there. is a lower row of weight numerals, being pounds, and an upper par- I allel row of total valve, numerals, being cents. Betweenthe two rows of numerals there is a single row or series of numerals 17. Both sides of the chart are similarly graduated and marked and the indicator 18 is provided with two points, as shown in Figs] 6 and 7, that move one on each side of the chart or plate 16 and point to the graduations and numerals on each side of said chart, so that both the customer and the merchant face identical charts with the same .graduations a1 1 the same indicator points to both at the same time. This makes the chart and the reading thereof very simple.

The indicating means, as herein shown, consists of the indicator 18 on a horizontal shaft 20 mountedwith suitable knifc-edged bearings on a rectangular frame 21 secured about midway of the casing between the top and bottom. A counter-balancing weight 2 extends from said shaft 20 in a direction calculated to counter-balance the indicator 18. An arm 23 extends to the i'ight from said shaft j and an arm 21L extends from said shaft in a substantially opposite direction .fluenced lever 25 through the connecting bar '26 that is pivotedat its lower end to the inner end of said lever 25 and atits upper end to said arm .Said indicator is controlled.

in its movement by an indicator-controlling lever30, the inner-end of which is laterally connected with the. connecting-bar 31 that at., its upper endis-pivoted to the arm 24. The arm 24 extends downwardly when the indicatorlS is at zero so that the downward pull on said arm has no appreciable influence on the indicatingmeans when it is at zero, but as the indicator is o)erated, as shown in Fig. 5, the outer end 0' the arm 21 gradually moves more and more to the left and thus avariable influence is exercised .on said indicator by said lever 30. The connecting bar 31 has a slot 32 at its lower end from which a cross-bar 33 from the lever 30 'loosely extends. A dash pot 34 isconnected by the stem 3:") with the inner end of the load-influenced 'lever25.

On the right hand end of the base 10 there is a'tubular stand 40'having two ful-' crum arms 41 projecting from the upper seen in Fig. 4. Upon the inner ends of these bearings 42 the, weight-influenced lever is fulcrumed. The righthand end of 'said lever 25 is divided and yoked to form two lateral arms 43 from which the knife edges 44 project that bear upon the bearings 42. To thecxtreme right hand end of said arms 43 there is ashallow pan 45 secured in which a small weight or weights may be placed for balancing said lever. From each side of the lever 25, or rather from each arm 43 thereof, there is .a laterally extending knife-edge 46,- to support the load-receiving member, so that said load-receiving member is su ported between the fulcrum points of said ever 25 and theinner end that is connected with the indicating means.

The load-receiving member 50 consists of a removable pan, which, as shown in Fig. 8, has a load or article 51 on it, and the pan supportr52which is centrally mounted on bearing piece 53, shown in Fig. 8. This hearing piece has a. centra'l bowliike por tion adaptetl to receive shot orother Weight forbalanc ing the scalehnd two oppositely extending bearing arms 54. that. rest upon gniderod 55 extending-glowii centrally from said-bearing piece-"'53 throii h the. hollow stend'wnml the base, and e its lower end is ipivot ally 'connectecl withthe herfifi that 19 is pivotedfto downwerdlyextending ermh? rom the "loose, as .shewn in Figs; i. 8.- This 'inechanism"-causes the, pan or lone; receiving niemhergtofalways have vertical movement.

As'the load is applied theinner end of the lever25 -moves downwardly and the other end movesupwardly, as shown in fig. The mechanism so far described will opcrate successfully as a-Weight scale Without. the addition hereafter to be described, and. by providing said scale with a computing or value chart, as is common in the art heretofore, said scale will operate 'as e. alue or computing scale. 1'; horizontal scale beam 60 is secured. to two arms 31 and62 extending out from the indicatorcontrolling lever 30. Said scale beam graduated with price-per-pounol marks and numerals andhas a poise-161 slidahle there: on. The spaces betweenfthe graduation marks diminish from left to right; or inversely with the price-per-pound numerals which increase from left to right. 7 v

As stated before, the indicator-controlling lever 30 is Weighted on its inner end so as to properly cooperate with the other parts so as to regulate the indicator. It is obvious that when the poise 161 is at 5 on the scale beam 60g that is to the left of the fulcrum of the lever 30, the Weight of the inner end of said lever will he correspondingly greater than when the poise is lIlOVGtl tothe right to the other numerals. The-effect of: the weight of the poise on theinner end. of the lever 39 anti on the indicating means iinishos as it is moved to the right; endit noted aim the scale beam 60 extends to the. right beyond the. fulcrum oi the lever 30 but the innerencl of the lever SO'is weighted sui ficientlv that when the poise 61 is moved to, its limit tothe rightit will fail to counterhale-nee the weighted encl'o't the leverv 30, so that said end of the lever is at all times 105 weightetl' or over-balanced but the over- Weight ofthe inner end ofthe lever 30 is rendered "variahle'hy the sliding poise 161.

in operation the scale ma he used 2 weight scale ore value scale. CWhn n =3. Weight'sesle'the poise 5.6 is let te D121. e the five cent mark, as shown in Fig. 1. When used as a valuescale the poise is moved to the price at which the article being weighed is sold. When the poise is moved away from the five cent mark then'the indicator does not truly indicate the weight but does truly indicate the'value. can readily determine both the weight value of the article first, by placing the poise at the five cent mark and reading the weight and then moving the poise to the price-perpound and then reading the total value. Or he can operate the scale to indicate either weight or value, if desired.

A great practical advantage in this scale is the location of the price-per-unit scale beam in a convenient horizontal position in front of the operator and where scalebeams and poises are usually located, that is, near the load-receiving pan or member, which is the most convenient and satisfactory place for locating such scale beam. Another advantage is that it enables the scale to be used with only one row of total value numerals instead of a very complicated chart which has heretofore been used in fan-shaped scales. Likewise, the arrangement is very convenient for indicating the same readings of the chart to both the operator and the purchaser, one being the reverse of the other and the chart being very simple and not calculated to confuse a purchaser or rendered diilicult for any purchaser to understand and read at once. By the flexible connection between the levers and the indicating means I mount herein any connection that is not rigid, whether it be a pivotal connection, as herein shown or a connection of the flexible means rigidly connected or pivotally connected at its ends. But while I have shown herein a stationary chart of weight and value graduations with a movable indicating means, certain features of this invention are not necessarily limited to such relative arrangement of said parts.
